REUBEN J GRUBB, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TOANDREW COOHRAN, OF SAME PLACE.

ART OF MANUFACTURING CARPETS, RUGS, MATS, 800.

SPECIFICATION forming part of Letters Patent No. 430,230, dated June 17,1890.

Application filed November 30, 1889. Serial No. 332,141. (No specimens.)

To all whom it may concern:

Be it known that I, REUBEN J. GRUBB, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in the Art of ManufacturingCarpets, Rugs, Mats, &c., which improve ment is fully set forth in thefollowing specification and accompanying drawings.

My invention relates to an improvement in the art of manufacturingcarpets, rugs, mats, &c., of the class formed of a body or piece of softrubber with tufts of yarn passed through the same and appearing on thefaces thereof,

producing an attractive, dense, yielding, dur-- able, and superiorarticle of the velvet or pile fabric.

The invention consists of a novel method of producing such carpet, rug,&c.

Figure 1 represents a perspective view of apparatus employed formanufacturinga carpet, rug, or mat in accordance with my invention. Fig.2 represents a face view of a piece of carpet, rug, or mat made by mymethod. Fig. 3 represents a section of a portion of the same.

' Similar letters of reference indicate corresponding parts in the threefigures.

Referring to the drawings, A designates a number of perforated boards orplates, be tween which are placed sheets B, of soft rubher, so that thelatter are sustained by the former, two of the boards or plates beingplaced between each two of the sheets B. It is obvious that the sheets Bmay be composed of other material than rubber, all that is requisitebeing that the foundation sheet shall have capacity for contractingaround the'openings or perforations formed therein, as will behereinafter described, to bind upon the tufts of pile inserted in suchopenings or perforations.

O designates a series of needles, which are supported in any suitablemanner and adapted to be aligned with the rows of openings in theplates, the said needles being connected with mechanism whereby they maybe moved in opposite directions through said openings. The needles 0 areheld by a reciprocating frame D, having racks E in mesh with order of agear-wheels F F and G, operated bya crankwheel H on a shaft J.

The operation is as follows: The needles are advanced through theopenings of the plates A, and they pierce the sheets B. Yarn.

or thread is then hooked or placed on the heads of the needles, and thelatter are returned, so that the yarn or thread is drawn through theopenings in the plates, and consequently through the perforations in thesheets B, the Work being continued until the required size of the'goodsis obtained, when a knife is passed between the adjacent plates, theyarn or threads being thus cut on opposite sides of the sheets, and theplates are then removed, leaving the yarns or threads projecting in theform of tufts. The plates being now disconnected from the sheets arereadily removed, and the tufts are steamed, whereby they swell or expandand form dense and close faces of yarn on opposite sides of the sheetsor bodies of the order of velvet or pile fabric, and are prevented fromleaving the sheets. The needles are comparatively thicker than the yarnor thread, so that they stretch the portions of the sheet around theopenings pierced by the said needles, and consequently when the yarn orthread is drawn through the sheets said portions contract upon or closearound the yarn or thread within the sheets, thus tightly holding thetufts and preventing separation of the same from the sheets. Thisholding action is also assisted by the yarn itself, in that when it isbeing drawn through the elastic sheets, it is stretched and thinned out.Then when it is at rest it comparatively resumes its normal condition,thus tightening in the holes of the sheet.

By employing yarn or stock of different colors and suitably passing thesame through proper openings of the plates fanciful patterns or designsmay be produced, a form of which is shown in Fig. 2.

Having thus described my invention, what 9 5 I claim as new, and desireto secure by Letters Patent, is-

1. The method of manufacturing a carpet, rug, mat, &c., consisting inplacing a piece of elastic material between perforated supports, 10o

carrying yarn or threads through the said supports and material, andcutting the yarn between the supports, substantially as described.

2. The method of manufacturing a carpet, rug, mat, &c., consisting inpassing yarn or thread through a piece of elastic material, cutting thesaid yarn or thread on opposite sides of the said piece, thereby formingtufts on the faces of the piece, and then steaming the tufts to swellthe same, substantially as described.

3. The method of manufacturing a carpet, rug, mat, &c., consisting insupporting a piece of elastic material between perforated supports,piercing said material so as to form openings therein corresponding inposition with the perforations in the supports, then passing yarn orthread through the coincident perforations and openings, next cuttingthe yarn on opposite sides of said material and supports, and therebyproducing tufts, and finally steaming the tufts, substantially as andfor the purpose set forth.
